Sequential turbocharged, clean-burning, and underrated is the BMW M57
In 2009, the BMW M57 diesel made its North American premiere in either the 335d sedan or the X5 SUV. The direct-injection inline-3.31-inch six’s bore and 3.54-inch stroke enable it to dispense 182 cubic inches (3.0L) of displacement. Off the showroom floor, it produced 265 horsepower at 4,200 rpm and 425 lb-ft of torque at 1,750 rpm, however timeslips of low 14-second passes at speeds over 95 mph in various 335d’s showed that the M57 was significantly undervalued from the factory. Its special sequential turbo technology allows for quick spool up and a power curve that remains stable until 5,000 rpm. Later, more on that.
0i – 2.8i M52
Brief explanation:
On BMW 3 series E36 vehicles, the M52 family of engines made their début in 1994. A evolution of the dependable and potent M50 is the M52. The adoption of an aluminum block, which decreased the weight by over 20 kg, is the primary distinction. The new engine’s lightweight exhaust manifold, chain tensioner, and connecting rods helped it to outweigh its predecessor by about 30 kg.
Engines in the M52 engine family come in working volumes of 2.0, 2.5, and 2.8 liters and produce 150, 170, and 193 horsepower, respectively. The S52, a 3.2-liter engine with 243 horsepower installed on the M3 and made for the North American market, is quite similar to the M52.
An improved M52TU engine first featured in the 1998 BMW 3 E46 series. It stands out due to the intake and exhaust valves’ employment of a variable valve timing mechanism (Double Vanos system). Only the intake shaft’s valve timing was altered in the initial engines. Although engine performance at low and medium speeds has increased, engine power has not altered.
The M52 family of engines are legendary in the field. It has a solid reputation for being robust and dependable, but it cannot withstand rough handling or negligent upkeep.
The long head of inline six-cylinder engines is vulnerable to bursting from overheating. It will, at best, rupture the cylinder head gasket. Frequent issues with the cooling system pump and the radiator fan motor are problematic. When buying another functional motor is the most efficient and economical option to repair, ignoring the symptoms of overheating might have disastrous effects.
Uneven engine functioning and a slow unwinding of the engine after warming up are symptoms of the issue. Failure may also be accompanied by challenging starting, requiring prolonged starter rotation. Cheaper alternatives will run you less than 1,500 rubles, while Siemens items would set you back roughly 3,000 rubles. Even for a non-specialized mechanic, replacement is not difficult.
Most engine components wear out more severely as they get older. Exhausted valve stem seals provide a significant contribution to the oil consumption.
Both the flagship BMW 7 series and the compact BMW 3 and Z3 series were equipped with M52 family engines.
In theory, it is appropriate to recommend any of the M52 engines. The engine’s 2.8-liter variant is the most popular. It is regarded as the most dependable and ensures user happiness. However, it’s getting harder and harder to find a well-groomed specimen every day.
You can select the M50 for previous model generations, particularly the BMW 3 E36 series.
Which of the current BMW engines is trustworthy?
Modern BMW engines are those that made their debut in vehicles built within the last 25 years. A secondhand BMW becomes a classic the older it gets.
One dependable BMW engine, the N52 inline-6 featured in the E90 325i, 328i, and 330i, has already been covered in detail. This engine isn’t ideal, but because it isn’t turbocharged, it doesn’t have the issues of the current N54 engine. Additionally, the N52 is free of the rod-bearing problem that plagued the E90 M3.
Make sure the BMW you’re looking at has the 2009 models’ upgraded cylinder head if it has a N52 engine. According to BMW Tuning, this eliminates the oil-related valve-tick problem that frequently arises in older vehicles. Automobiles manufactured in 2008 and earlier may experience steering lock and ABS module failure.
The M54 inline-6 is another dependable contemporary BMW engine. This engine is found in the 2000–2006 E46 3 Series, as well as modern Z3 and Z4 roadsters and X3 and X5 SUVs, according to BMW Tuning. And it has a reputation for performing dependably even after traveling a great deal of distance.
Having saying that, the M54 engine isn’t entirely faultless. It includes BMW’s VANOS technology, which controls the valvetrain, just like the N52. The system’s solenoids and seals deteriorate and fail over time. The DISA valve on the intake manifold and the plastic valve cover both have a similar tendency to deteriorate.
But contemporary spare components come in better and more durable materials. Additionally, certain M54s have loose oil pump nuts, which could fall off and cause an engine to fail. However, according to BMW Tuning, most have already been better secured with Loctite.
The M44 4-cylinder engine, which can be found in the 1996-1999 BMW Z3 and E36 318ti, is the last option, according to Turner Motorsports. According to UnixNerd, the M44 is descended from the M10 4-cylinder used in the E30 3 Series and was preceded by the M42 and M40 engines.
Although the S14 engine in the M10 and E30 M3 is quite robust, according to BimmerLife, the M44 is more tolerable. Not the least of which is that it features an OBD-II port that is current. It’s also a reliable engine, according to UnixNerd, with the exception of certain age-related gasket and tubing problems.
Engine 5N52
Given that it is a naturally aspirated straight-six engine offered by the BMW market, this engine is among the most cutting-edge. Of all the naturally aspirated straight-six engines that BMW has ever built, it is the most advanced, produces the most output, and is quite simply the most refined.
From 2004 to 2015, when turbocharged engines finally took its place, this engine was readily accessible. They are frequently reported to be present in BMW E.93 series and E.636 series vehicles. It was the first water-cooled engine ever constructed from magnesium and aluminum, and it took the place of the M54.
Over the years, these engines have gradually undergone certain adjustments and tuning. For instance, the 2.5-liter displacement 325 produced outputs varying from 174 horsepower up to 201 horsepower before reaching 215 horsepower in E90 versions.
In its last and most advanced configuration, the 3-liter engines in the 330 could produce up to 268 horsepower. These vehicles were powerful and automatic, so you didn’t need a turbo because purchasing a 330 provided you a silky smooth drive train, all the performance economy, and dependability you could possibly want.
Is the BMW diesel engine reliable?
There are benefits and drawbacks to owning a BMW with a diesel engine, so let’s look at reliability to round out the list of additional things to think about. The 530d and 535d BMW Series 5 diesel versions include the same features that make the BMW Series 5 a popular pick with customers, but the diesel engines feature a 6-cylinder turbo diesel engine. The BMW contemporary diesel engine has a number of noteworthy benefits, as we have already mentioned.
Modern diesel engines are far better built and require less maintenance than diesel engines from the past. BMW achieved this feat once more by providing a solid diesel engine in the 530d and 535d.
Consumer Reports rates the engine’s overall reliability for the 2014 model year as “below average,” despite the fact that it may be well-built. As time went on, the 2015 and 2016 models became more dependable, achieving ratings of “above average” for the 535d model years 2015 and 2016 and “average” for the 535d model years 2015 and 2016, respectively. As a result, while you can save money on gasoline, you might also have to do more maintenance than usual, which is common for BMWs generally and not just the F10 diesels.
Therefore, if dependability is a high priority for you, the diesel possibilities might not be the ideal fit for you; instead, you might prefer to go with a commonplace petrol engine, of which BMW provides a wide range. However, if you want an engine that is strong and aggressive and reliability is not a top priority, it can be the right choice for you.

Which BMW 3 Series engine is the best?
The 318d and 320d four-cylinder diesel versions, in particular if you travel a lot of miles, are so fuel-efficient while yet offering plenty of performance that they remain popular even though diesel cars aren’t quite as popular as they were a few years ago.
The four-cylinder 320i and 330i petrol engines offer sporty performance without significantly losing fuel economy as compared to the diesel counterparts if you drive less kilometres.
If power and performance are your top priorities, the top-of-the-line M340i xDrive with its powerful 3.0 litre six-cylinder engine is definitely the best option. Although the M340d’s diesel engine isn’t quite as powerful, it is almost as quick. But in our opinion, the M340i with a gasoline engine is the more enjoyable vehicle to drive.
The sporty-looking M Sport trim level is by far the most popular when it comes to trim levels, but the lower-spec SE and Sport trims are still attractive and well-equipped options.
Is the BMW 3.0 diesel an effective motor?
It’s an engine that’s rock-solid, incredibly fuel-efficient, and now quite affordable, but some of you didn’t know it existed until recently. The BMW 3.0L M57 inline-six diesel engine has arguably as much performance potential as a Cummins common-rail engine. It made its American debut in 2008 (as a 2009 model offered in the 335d) and came equipped with a special sequential turbo system (compounds), 265 horsepower, and 425 lb-ft of twist—numbers that would turn out to be underwhelming. These fast cars have excellent driveability and can accelerate from 0 to 60 mph in 5.7 seconds. They can also complete the quarter mile in low-14-second intervals with their standard engines.
When the aftermarket got a hold of the M57’s I-6 architecture and robust internals, the engine’s true potential was eventually realized. The platform has demonstrated its ability to support north of 700 hp at the wheels without the need for bottom-end improvements after the platform’s issues with the emissions system and a few other weak links have been fixed. We spoke with S&S Diesel Motorsport, the common-rail gurus who create larger piezo injectors for them, and Santjer Performance, maker of the most potent 335d in the world, to get the full lowdown on what the M57 is capable of. We immediately discovered that you can create Hellcat-like power for far less than $20,000 (including the cost of the car) without even upgrading the factory transmission. And you can enjoy yourself while driving a vehicle that can achieve almost 40 mpg on the interstate.
Is a BMW diesel better than a petrol one?
- Previously, diesel engines were also believed to be slower, noisier, and less environmentally friendly than their petrol-powered counterparts. However, when you consider the technology used in modern car construction, this is no longer the case. As part of the EfficientDynamics program, the BMW Group has recently made considerable investments in improving and optimizing its diesel engine technology.
- New turbo-diesel engine generations are posing a serious threat to their petrol counterparts, according to several automakers. They are comparable to them in terms of performance and noise levels in addition to smoothness.
- Diesels are excellent for overtaking and towing because they create strong torque (pulling power) at low speeds.
- Typically, diesel engines will get more miles per gallon than their petrol counterparts.
- Diesel drivers benefit from lower road tax bands than petrol car owners since diesels emit less CO2.
